I've been paying attention to what deviantart does, or let's say "displays" whenever you upload a picture, which are details of the image you've uploaded, like camera make, model, shutter speed, etc.

My question is, is it somehow possible to get this kind of data by using PHP? I'm aware of the fact that you're able to modify pictures using PHP, for example you can integrate watermarks, text over an image, resize the image, but that's not what I'm asking for, just as a note.

If it's not possible by using PHP, what does deviantart use to get this kind of data? They even have the image editing tool name you've used.
